    Hello Hope this help here is how I manage to configure GPU Passthrough. In my case I have follow the documentation on XCP-ng website : https://docs.xcp-ng.org/compute/ To sum up with XOA 8.3 here is what I did: ssh to XCP host, to identify the GPU PCI and run lspci to find my GPU. [root@xen ~]# lspci ... 0f:00.0 VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3090] (rev a1) Then disable the GPU for being used by XCP-ng itself( Dom0) using the XCP-ng uuid [root@xen ~]# xe pci-list uuid ( RO) : 7970825f-dd1c-c270-93a3-6761f00e1362 vendor-name ( RO): NVIDIA Corporation device-name ( RO): GA102 [GeForce RTX 3090] pci-id ( RO): 0000:0f:00.0 xe pci-disable-dom0-access uuid=<pci uuid> 3 reboot the XCP-ng host 4 Then from XOA attached the PCI related to my GPU to my guest VM. [image: 1770098359041-4dcb36ff-b29c-4d0b-b113-127243928dd6-image-resized.png] [image: 1770098407490-3f29792e-154f-40fc-b554-323d8ef87e52-image.png] [image: 1770098436148-7208a3ff-68e2-4c50-9dc8-2edde9ac8d76-image-resized.png] 5 install official Nvidia drivers ( closed source ) and have then the card available in the guest. [image: 1770098585851-9bcbea25-b83b-4a26-a085-b58236c83f84-image.png] [image: 1770098624052-88f35aba-bd75-4da6-9cbf-d62bb8994ef7-image.png] What I didn't do is adding a vGPU in the guest configuration: [image: 1770098900399-63b2a458-9758-40d1-9515-48b5cd4615ea-image.png] I did it some times ago, also I don't recall having to do any specific configuration in the Bios to make this work. PS: I have an issue, I don't have output to the Display port or HDMI of this video card, which is not a blocker for me as that's not my immediate needs. Best.

    @bleader Hopefully the palm print on my forehead isn't visible from where you are sitting. Of course the interface needs an IP address. In my defense, normally for something like this, I wouldn't put it on the bonded interface with all the trunked VLAN's for guest traffic (we don't give that one an IP) and it would go on the other bonded interface that isn't trunked and does get an IP, but these are test hosts and I didn't set up the other bond, so it is pulling double duty. I was able to set the IP's and get SDN working. Thanks!

    What is the purpose of this discussion? Could this feature integrate XCP-ng? We are looking for a new virtualization solution. Oracle is a bottleneck for backups. We tested the backup with the Veeam agent, which appears to be successful. However, replication is not possible for this Oracle point via Veeam.

    This filter works in XOA -- other:XenCenter.CustomFields.export_vga:"true" You can try this with curl -- curl -k -b authenticationToken=$tk "https://xoa.pc.scharp.org/rest/v0/vms?fields=name_label%2Cpower_state%2Cuuid&filter=other%3AXenCenter.CustomFields.export_vga%3A%22true%22"

    Kubernetes CCM for Xen Orchestra v1.0.0-rc.1 We’re shipping v1.0.0-rc.1, our first release candidate on the road to a stable 1.0.0! This RC is feature-complete and ready for real-world use. Please try it out and share any feedback—bugs, regressions, or usability notes—so we can polish the final release. Thank you for testing and helping us! https://github.com/vatesfr/xenorchestra-cloud-controller-manager/releases/tag/v1.0.0-rc.1 Golang SDK for Xen Orchestra v1.11.0 SDK v2: VM and Task services now match the latest REST API. Host service has been added for host data retrieval. Integration tests have also been strengthened to boost reliability. The v2 SDK is gradually becoming our main library for all the other DevOps tools (Kubernetes drivers, Terraform provider…). There are BREAKING CAHNGES in the v2 SDK, so please read the release notes carefully. Remember that the v2 SDK is a beta version and can be subject to significant changes. The current semantic versioning we use is mostly for the v1 SDK. When the v2 SDK becomes stable, the major version number will increase. https://github.com/vatesfr/xenorchestra-go-sdk/releases/tag/v1.11.0

    @olivierlambert Thanks. --rename isn't mentioned in the KB. If I don't see something in the next week or two, I might be able to test it in a lab and then propose an update via a github fork.

    Have you read the link I've sent? It explains exactly the reasons and answer your question You can imagine that if we have hundreds of 3rd party scripts, each doing their own way to install, it means we'll have to de facto support them all, despite it's unrelated to Xen Orchestra itself. Which means spending resources instead of working on Xen Orchestra directly (or fixing XO bugs). That's why it's preferable to open a ticket in the Github repo of the script creator, because that's exactly there you'll find the right answer, and also making sure the script creator could even fix their scripts if needed. If you need community support in here, you have to install it by following the official documentation: https://docs.xen-orchestra.com/installation#from-the-sources

    Just a reminder for myself, or other people in need in the future thanks again for all people who helped me understanding this Had to reinstall my entire XCP system, and almost forget how to configure Ldap plugin to only allow my admin accout to login So here's my Ldap plugin conf, to allow only admin user (member of specific group) to login. my AD is a windows 2K19 server with active directory without ssl. URI : ldap://dc.domain.net:389 no certificate info base : dc=domain,dc=net Credential : Fill = tick DN = full DN of service user (CN=xen,OU=service_account,DC=domain,DC=net) password = password of this account it's a simple account with no specific right, can only read AD and login User Filter, where it can stuck (&(sAMAccountName={{name}})(memberOf=CN=SG-XCP_Admin,OU=service_account,DC=domain,DC=net)) in real my OU have spaces inside their name, it work anyway. SG-XCP_Admin is a security group having my admin users inside ID Attribute : sAMAccountName and that's all.

    @Andrew many thanks. As do I. See my OP. A failed build doesn't break XO. It leaves the previous successful build in place. My post wasn't to ask how to fix my problem, but to point out the issue to others who might care to know (see my last post). Cheers.

    This is an old thread, but I ran into this myself recently. While there is a link to deleting the entire XO configuration, I think I fixed it with a less drastic solution. Remember: I'm just a random dude on the internet posting dangerous commands to try. It worked for me, but your mileage might vary. I run Xen Orchestra in a container (Xen Orchestra, commit e8733 at the time of writing). So I got a command line in the container with: docker exec -it xoa bash Then I ran redis-cli to get a redis command prompt. I typed KEYS * to get a list of keys. One key I saw was: 7) xo:server_host:172.30.0.214". That's the IP of the host I was trying to join (the master of a single-host pool). So I ran: del xo:server_host:172.30.0.214 Then I restarted my container with docker restart xoa. After that, I was able to successfully add the host to Xen Orchestra. Maybe this will help someone else. It got me working again.

    @jsox79 No I did not. Disclaimer - I inherited this FreePBX system and don't know a whole lot about it. Once I got it to boot, I tested by calling my cell from a desk phone and making a page, and both worked as expected so I'm considering everything to be working. Didn't realize re-registering modules was something I may have needed to do.

    Bit of a necro-post, but we're mid migration of storage/VM hosts/pools. I have a single win11 VM that's UEFI (not secure boot). It runs just fine on our old 8.1 server that we're migrating off of. If I provision a new UEFI VM on the new pool and point it at the shared storage VHD, it refuses to boot with the same "The emulator required to run this VM..." error OP posted. I've tried restarting the toolstack and "updating the Secure Boot certs" on the host server. Any guidance very much welcomed, I was unaware that this VM wasn't booting on the new pool (the VM is off a lot of the time), and we're a couple weeks from this project completing (and the old server being WEEEd).

    Not with XOA then (yet). We might switch XOA to UEFI in the future for that. If you are using XO from the source, sure, you can do that

    @olivierlambert The only thing I can think of from newer kernels is NFS options like nconnect=xx for hopefully more speed in the day to day range of duties. As of the pre-LTS, this still wasn't in 8.3. I haven't checked after LTS.

    @bleader Hi, After a restart of the entire host, port 6640 is now listed when I trigger ss. But, unfortunatly, tunnels are not working, every VM on this host loose connection to other in the same sdn network. Exemple with an ping between two hosts : 2025-10-09T12:22:54.781Z|00026|tunnel(handler1)|WARN|receive tunnel port not found (arp,tun_id=0x1f1,tun_src=192.0.0.1,tun_dst=192.0.0.3,tun_ipv6_src=::,tun_ipv6_dst=::,tun_gbp_id=0,tun_gbp_flags=0,tun_tos=0,tun_ttl=64,tun_erspan_ver=0,gtpu_flags=0,gtpu_msgtype=0,tun_flags=key,in_port=33,vlan_tci=0x0000,dl_src=56:30:10:5c:4d:ad,dl_dst=ff:ff:ff:ff:ff:ff,arp_spa=192.168.10.10,arp_tpa=192.168.10.20,arp_op=1,arp_sha=56:30:10:5c:4d:ad,arp_tha=00:00:00:00:00:00) 2025-10-09T12:22:54.781Z|00027|ofproto_dpif_upcall(handler1)|INFO|Dropped 61 log messages in last 59 seconds (most recently, 1 seconds ago) due to excessive rate 2025-10-09T12:22:54.781Z|00028|ofproto_dpif_upcall(handler1)|INFO|received packet on unassociated datapath port 33 If I migrate the VM on the third host to another, network came back. This is very strange, because the network I've choose to test it is one of firt of all created, not last one, so it have worked before, and not now. I don't understand why and what to do...
